Synthesis of Thieno[2,3‐c]pyridine Derivatives by 1,2,3‐Triazole‐Mediated Metal‐Free Denitrogenative Transformation Reaction [PDF]

ChemistryOpen
In this study, we report the synthesis of thieno[2,3‐c]pyridine derivatives by a metal‐free method via fused 1,2,3‐triazoles. In the synthesis of this skeleton using a three‐step method, we first obtained 1‐(2,2‐dimethoxyethyl)‐5‐(thiophen‐2‐yl)‐1H‐1,2,3‐

Sources, Transformations, Syntheses, and Bioactivities of Monoterpene Pyridine Alkaloids and Cyclopenta[c]pyridine Derivatives [PDF]

Molecules, 2022
Monoterpene pyridine alkaloids (MTPAs) are alkaloids derived from iridoid glycosides (IGs). The common molecular structure of MTPAs is the pyridine ring, while some of them have a cyclopenta[c]pyridine skeleton.

Metastable Transitions in Pyridine and Pyridine Derivatives [PDF]

Zeitschrift für Naturforschung A, 1981
The kinetic energy released in metastable transitions in pyridine, 2, 3, 4 acetylpyridine and 2, 3, 4 aminopyridine differs for the different isomers. This indicates that the dissociation path-way of these compounds depends on the position of the nitrogen atom in the isomer.
